Connecting device to antenna housings

Abstract

A connection device on an antenna housings includes a circular mounting platform, a covering cap, and a screw bolt. The circular mounting platform is configured to receive an antenna board on the top side. The bottom side of the mounting platform is provided with reinforcement ribs running radially toward the center. The covering cap is configured to completely cover the mounting platform. The screw-bolt is situated at the center of the mounting platform, and is configured to be inserted into an antenna housing carrier. The connection device is a rotary/latching connection.

The invention claimed is: 
     
       1. A connection device on an antenna housings comprising:
 a circular mounting platform configured to receive an antenna board on the top side, wherein the bottom side of the mounting platform is provided with reinforcement ribs running radially toward the center; 
 a covering cap configured to completely cover the mounting platform; and 
 a screw-bolt situated at the center of the mounting platform, and being configured to be inserted into an antenna housing carrier, wherein the connection device formed between the covering cap and mounting platform is a rotary/latching connection having:
 i) a rotary position, which is locked but releasable in a nondestructive manner, and 
 ii) a latching position, which is locked and not releasable by further rotation. 
 
 
     
     
       2. The connection device according to  claim 1 , wherein
 the screw-bolt is formed as a hollow bolt on the bottom side of the mounting platform, standing perpendicular to it, and 
 the screw thread has two flats situated parallel to each other. 
 
     
     
       3. The connection device according to  claim 2 , wherein the plane of symmetry of the flats points toward a region on the bottom side of the mounting platform which is free of reinforcement ribs. 
     
     
       4. The connection device according to  claim 2 , wherein
 a fork tool grasping the flats is provided with a flat grip arm, in whose surface is arranged a cylinder bolt engaging in a bore in the antenna housing carrier after a corresponding rotation of the mounting platform. 
 
     
     
       5. The connection device according to  claim 4 , wherein
 the screw-bolt is surrounded by an O-ring arranged in the bottom side of the mounting platform configured to seal it off against the antenna housing carrier, and 
 the cylinder bolt arranged on the grip arm of the fork tool is surrounded by a smaller O-ring arranged in the grip arm configured to seal it off against the antenna housing carrier. 
 
     
     
       6. The connection device according to  claim 5 , wherein
 an encircling bearing surface is arranged on the inside of the covering cap at a distance from the cap rim, 
 between the bearing surface and cap rim are arranged segment-shaped guide strips of almost the same width as the bearing surface for the rotatable insertion of the mounting platform, 
 the distance between the bearing surface and the guide strips is adapted to the thickness of the surface of the mounting platform, and 
 segment-shaped cutouts adapted to the guide strip in length and width are introduced into the circumferential rim of the mounting platform for the placement of the mounting platform on the bearing surface. 
 
     
     
       7. The connection device according to  claim 5 , wherein
 an abutment web bounding the rotation is introduced in the rotary direction between the guide strip and the bearing surface. 
 
     
     
       8. The connection device according to  claim 5 , wherein
 angle segments are formed on the cutouts, perpendicular to the surface of the mounting platform, which overlap the guide strips upon rotation between covering cap and mounting platform, and 
 the angle segments are adapted in their thickness in the overlap region to the distance between the guide strips and the cap rim. 
 
     
     
       9. The connection device according to  claim 8 , wherein
 an inwardly pointing leading ramp is introduced into the wall of the covering cap before the abutment web in the rotary direction, with a step edge spaced away from the abutment web, and 
 a radially outward pointing latching element, which is displaceable across the step edge, is formed on the segments of the mounting platform engaging between guide strip and bearing surface on the front segment region pointing toward the abutment web in the rotary direction. 
 
     
     
       10. The connection device according to  claim 8 , wherein
 the size of the latching element is adapted to the distance of the step edge from the abutment web. 
 
     
     
       11. The connection device according to  claim 8 , wherein
 the latching element has a resilient tongue having a spring path in the plane of the mounting platform.
